Reactor with an annular adsorptively active bed and an annular inert bed

摘要

A reactor has a jacket (1), and two annular beds (6). One bed has a chemically and or adsorptively active material (active bed) and one bed (7) has a material which is inert with respect to the chemical reaction that is to be carried out in the reactor (inert bed). The first bed (6) surrounds the second bed (7). The beds are separated from one another by a gas-permeable and or liquid-permeable barrier. A gas feed gas exhaust space (4) is between the jacket and the active bed (6) or optionally between the jacket and an inert bed surrounding the active bed. Gas feed gas exhaust in the form of a hollow central column (2) is provided where the inert bed (7) partially fills a space between and adjacent to the hollow central column and the active bed. The active bed has an inner entry or exit area of a predetermined height and the inert bed extends over 10% of the predetermined height of the inner entry or exit. The inert bed extends over the entire predetermined height of the inner entry or exit area of the active bed.
